What are atoms with greatly differing electronegativity values expected to form?
an ionic bond
What do covalent bonds generally form if the difference in electronegativity values between two atoms is less than 0.4 nonpolar?
true
How does a ionic compound form?
An ionic compound forms when atoms of an element of low electronegativity transfer one or more electrons per atom to atoms of an element of high electronegativity. The resulting cations, formed from the atoms of the element of low electronegativity, and anions, formed from the element of high electronegativity, are held together by mutual electrostatic attractions to form the ionic compound.
What causes an ionic bond form?
A large difference in electronegativity values between the two atoms forming the bond will cause the bond to be ionic. The electrons from the less electronegative atom will be completely donated to the atom with the greater electronegativity. This occurs when a metal and a non metal bond.
Atoms with electronegativity differences below 0.4 generally form covalent bonds?
TRUE

What do covalent bonds generally form if the difference in electronegativity values between two atoms is less than 0.4 nonpolar?
true
What kind of bond forms through sharing of electrons?
A covalent bond forms when atoms share electrons. If two atoms have similar electronegativity values (general rule of thumb is if their electronegativity values is less than 1.67) than the two atoms are more likely to share electrons. This tends to happen between two non-metals. Ionic bonds form between two atoms with electronegativity value differences greater than 1.67. They involve a transfer of electrons. This occurs between a metal and nonmetal.

TRUE
What does electronegativity means in the periodic table?
Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond. It increases across a period from left to right and decreases down a group in the periodic table. Elements with high electronegativity tend to form negative ions, while elements with low electronegativity tend to form positive ions in chemical compounds.
What are the four types of chemical bonds?
Ionic Bonds-form when two atoms have a large difference in electronegativity. Covalent Bonds-form when two atoms have a very small difference in electronegativity. Polar Covalent Bonds- form when two elements bond with a moderate difference in electronegativity. Fall between ionic and covalent. Metallic Bonds-form in and between metals
Are Weak chemical bonds form only between atoms of similar electronegativity?
yes
Atoms with electronegativity differences below 0.4 generally form covalent bonds.?
TRUE
Is two carbon atoms polar?
No, Two atoms of the same type will form a nonpolar bond because there is zero difference in electronegativity.
Two atoms with an electronegativity difference of 0.4 form a bond that is?
covalent, because electrons are shared
